son-in-law has HP A810N desktop Athlon 64 3300+ 2.4Ghz processor with 2GB ram. He wants to upgrade his integrated video SiS Mirage 2 128mb to something better. MOB is ASUS K8S-LA. Quick scan shows people recommending GeForce 6200 LE 512mb or NVIDIA 6600gt, or NVIDIA FX5500 or ATI 5250 or GTX 295 or GeForce 7600gt or Radeon HD3650. He has both AGP slot and PCI slot available. I felt AGP was best but which card.
